GEORGE R. YOUNG, OF RIDGEWVOUD, NEW JERSEY.

TIME DAMPER APPARATUS.

SPECIFICATION forming part of Letters Patent No. 781,170, dated January 31, 1905.

Application filed March 14, 1904. serial No. 198,062.

To all whom it may concern:

Be it known that I, GEORGE R. YOUNG, a citizen of the United States, and a resident of Ridgewood, in the county of Bergen and State of New Jersey, have invented certain new and useful Improvements in Time Damper Apparatus, of which the following isa specification.

This invention relates to time damper apparatus, and has for its object means with which the draft appurtenances, dampers, valves, or doors of a furnace, heater, boiler, and the like can be both opened and closed by timereleasing apparatus or mechanism.

The organization of the invention is characterized by embodying the double function of both opening and checking or checking and opening or either openiii'gor checking independently of each other the draft of a furnace, heater, and the like by operating in conjunction with time release mechanism such as is embodied in an ordinary clock or other timepiece and the like.

The essential elements of the invention are a timepiece with release mechanisms, and a movable support arranged to be moved by one or both of said mechanisms. The movable support is weighted so as not to quite counterbalance the weights of' the dampers, doors, and the like connected therewith, thereby enabling its change of position when released by a time-release mechanism. A second release mechanism in the timepiece also coacts with the movable support, reversing the position of the movable support and the appurtenances after having moved with the first release mechanism.

This invention isa companion patent to my application, Serial No. 188,687, filed January 12, 1903.

In the drawings, Figure 1 represents an elevation of the invention applied to a steamheater on a reduced scale. Fig. 2 is a front elevation of a'portion of the appurtenances directly connected to a timepiece, the latter having only the release mechanisms shown and a section of Fig. 3 as on the line 3 y. Fig. 3 shows a partial top view of Fig. 2. Fig. 3 represents a partial front view of a fragmentary modified portion of the appurtenances connected with the timepiece. Fig. 3 is a section of Fig. 3 on the line 00 m. Fig. 3 is a front view of one of the elements shown in Fig. 3. Fig. 4 represents an elevation of the movable support, on a scale somewhat smaller than the size of Fig. 2, with its directly-accompanying appurtenances. Fig. 5 shows a section of Fig. 4; on the line :0 m. Fig. 6 is a partial top view of Fig. 1. Figs. 7 and 8 are reproductions of Fig. 4 with the positions of the moving elements changed. Fig. 9 represents a partial reproduction of Fig. 4: with further changed positions for the movable elements. Fig. 10 shows a partial reproduction of Fig. 4 with a modification. Figull is a portion of Fig. 10 on an enlarged scale. Fig. 12 represents a section of Fig. 11 on the line 00 m Fig. 13 is an elevation of a counterweighted bell-crank. Fig. 14 is a section of Fig. 13 on the line .70 00 Fig. 15 shows a side view of Fig. 13.

Referring to Figs. 1, 4, and 7 particularly, a timepiece A is shown fastened to a bracket B by means of screws 6, that enter legs C of the said timepiece. A movable support- D is pivoted to the vertical leg 6 of the bracket B, a stop (Z extending from the said bracket, preventing it to be turned to quite a vertical position, and the support is gearedwith one of the release mechanisms, of which latter the key D is a portion. A driving-sector F is also pivoted to the vertical leg 6' of the bracket B and is prevented fromassuming a vertical position by the stop F which extends from the said bracket. It is in gear with a second release mechanism, of which latter the key F is a portion. A chain H exten'ds from curved guide (Z of the movable support D to a pulley H and then leads to the guide 71 of the bell-crank I. A chain jextends from the said bell-crank and leads to the front door J of steam-heater J J. A movable lever I is pivoted on the bell-crank I, the end of the lever carrying a chain k, that leads over a pulley L and connects with the rear damper M. The said chain 1c also connects with one end of the counterweighted lever m of the regulator M, and a chain m leads from the opposite end of the lever m to the draft-door N.

Referring now particularly to Figs. 2 and 3, the front and rear frame-plates A A of the timepiece A are shown to support the hour-post a, on which latter is mounted the spur-gear a, which meshes with the pinions a and f, the former meshing with the gear a and the latter with the gear f. The spindle a of the gear (6 carries the pinion a, that meshes with the gear (0 and the latter meshes with the pinion a the spindle a of which carries the key D. The spindlef of the gear f carries the pinion f that meshes with the gear f the latter meshing with the pinion f", the spindle f of the latter supporting the key F. On the spindle a there is carried a ring a with a beveled hook a. From wheel (0* projects the barrel (0, and both the latter can move along the axis of the spindle a A spring a presses the said wheel, with barrel, outwardly in direction of the arrow. The barrel (0 is suitably notched for the said hook it, and while the gear a, with its barrel, is being propelled by the train of gearing from the hour-post a, the hook a bearing against the said barrel, the wheel a maintains the end a of the springa againstafan-wheel a, through an opening in the plate A. When the notch in the barrel (0 comes opposite the hook a the wheel a", with its barrel, moves along its axis in the direction of the arrow, and the end a of the spring a releases the fan-wheel a. The said fan-wheel a is supported on the spindle a, which also carries the pinion a, that meshes with the gear a, carried on the spindle a, and on the latter is secured the pinion (0 that meshes with the gear (L21, that fits loosely on its spindle (L22. A ratchet-wheel (0 is fastened to the spindle c0 and a pawl a, with its spring a is carried on the wheel a. On the spindle f there is carried a ring from which projects a beveled hook f and the spur-gearj" carries the barrel f, that is notched for the hook f. A spring f, with one of its ends fastened to the plate A and its free end f capable of extending through an opening in the said plate, can engage with afan-wheel f The body portion of the spring bears against the wheel f to press it forward along its axis in the direction of the arrow, and when the hook f by virtue of the turning of the wheel f engages in the notch of the barrel f the spring f releases the fan-wheel f. On the spindle f of the fan-wheel there is mounted the pinion f that meshes with the spur-gear f and on the spindle f of the latter there is located the pinion f that meshes with the gear f which latter is loose on the spindle f A ratchet-wheelf is fastened to the spindle f and a pawl f with its spring a f is carried on the spur-gear f Referring now particularly to Figs. 2 to 12, the movable support D is shown to comprise the disk (Z, with the teeth cl extending from a portion of its circumference. A handle (Z ex- 5 tends from the said disk, and ahub (Z 3 projects from the middle portion thereof. A pivot cl extends through the hub and is secured in the vertical member 6 of the bracket B. From the disk (Z extends the internal gear (Z and the arms 6 (Z which latter support the curved guide (Z A counterweight (Z is adjustably secured to the handle (Z by means of the screw (Z The driving-sector F, with teeth F, is supported by the arms F extending from the hub F, and the said arms also support the internal gear F". The handle F extends from the hub F and has the counterweight F adjustably secured thereon by means of the screw F. A pivot F holds the sector, with its appurtenances, to the vertical member 5 of the bracket B. A pinion F on the spindle f which latter extends through the frame-plate A of the timepiece, meshes with the internal gear F, and a pinion (Z on the spindle (v meshes with the internal gear (Z the spindle (4 also passing through the said plate A The lower and horizontal member 6 of the bracket B has the openings 6 If to respectively allow the handles F (Z to swing therein and the opening 6 to permit the chain H to pass therethrough. Buffers with plungers O and springs O are secured to the member 6 in the openings 0 and b to prevent jar when the handles F and (Z are dropped.

In Figs. 10 to 12 there is shown a modification of the movable support, which in this case is designated by the letter F. The disk portion 7), as before, carries an internal gear p, but has a cavity 19 on the sides of which extend the lugs 19 for the pin pi that carries the movable tooth p. A tooth 19 adjacent to the tooth 19 has extending therefrom the stop p and a spring 19 extends from a wall of the cavity 39 and bears on the rear end of the said movable tooth. Thedriving-sector F remains the same, and one of its end teeth F is shown in contact with the movable tooth p.

Referring now to Figs. 1 and 13 to 15, the bell-crank I is pivoted in a hanger I, which has extending from its upper end the pin and atits lower portion is made U-shaped for the pin The leg 1 extends horizontally from its vertical portion and has a pin 2' for a lever 1 which has one of its ends 2' extending through an opening 91 formed near the apex of the bell-crank 1. A curved guide unites the arms of the bell-crank, and an eyelet i" is formed at one end thereof. Holes or pins i for securing the chain it" are at the free end of lever 1 It will be evident that when the bell crank is raised in the direction of the arrow, Fig. 13, that the chain H, Fig. 1, will move up and that the free end of the lever I will move in the direction of the arrow shown in Fig. 14:. On the arm 6 of the crank I is pivoted a lever a arranged to swing over a sector 2', extending from the arm i A weight 1* can be secured in different positions on the arm i by means of the ITO thumb-screw 2 and the arm can be adjustably secured on the sector i by means of the bolt 6, clamping the arm i in various posi tions by virtue of the slote' in the said sector.

To operate the invention, it is customary to arrange the elements to operate in one direction at a predetermined time and in an opposite direction in an interval thereafter. Ve \vill first suppose that the draft is closed. as shown in Fig. I, and that it is desired to first open the draft and then to close it. To open the draft, the chain H must be lowered, and to check the draft it must be again raised. To obtain the location and disposition of the elements shown in Fig. l, the movable support D must have been turned down to the right,

with its teeth out of mesh with the teeth of the driving-sector F. It can be turned to this position without coacting with the fan-wheel, as the ratchet-wheel (0 in turning to the right with the handle 622 slips away from the pawl a on the wheel a The pointer on the dial D having now been set at a predetermin ed time the hook a will enter the depression in the barrel (0 at the said time by the operation of the train of gearing between the hour-post a and the barrel a This permits the hook end a of the spring a to become disengaged from the fan-wheel 64, allowing the latter to turn, and with it the train of gearing, between the said fan-wheel and the gear 21 and pinion d permitting the handle (Z to be pulled up by reason of the weight supported by the chain H. The said chain H is lowered, and the movable support will take the position shown in Fig. 7. The drivingsector F we have supposed to be turned to the position shown in Fig. 1, and which can be secured by hand, as in turning from left to right the ratchet-wheel f turns under and away from the pawl f. It will be noted that the teeth (Z and F are out of line of contact with each other. The next operation will be to raise the chain H, and the pointer of the dial F" having been set ata predetermined time when the hour-post by means of the gearing between the same and thebarrel f 9 brings the depression in the latter opposite the hook f the hook end f of the spring f releases the fan-wheel f, and the weight F being sufficiently heavy throws the handle F to the left, so that the driving-sector turns up, and with it the toothed support D, both as shown in Fig. 9, and the chain H is raised, as required. in Fig. 8 the position of the elements show the last tooth of the driving-sector engaged with the last tooth of the movable support as they are both turning up to become disengaged, and when the relative positions are obtained, as shown in Fig. 9, the teeth will be wellclear of each other on account of the momentum of the moving elements. We will now suppose the draft to be open, with the dampers in positions opposite to those shown in Fig. 1, and

it is required to check the draft, and then open it again. In such a case the door J and damper M will be found closed and the door N open. The first operation of the apparatus will be to raise the chain H and afterward to lower it.

To start with, the moving elements will have to be located, as shown in Fig. 7, and if they are not so disposed the driving-sector can be so located that is, turned up by the ratchetwheel f 21 sliding under the pawl f 22 when raising the handle F". If the handle (Z is down,

it can be raised by hand by first disengaging the spring a and the fan-wheel a and engaging them again when the handle d has been raised by means of the key D. The elements can now be supposed located, as shown in Fig. 7 and both release mechanisms having been properly set, the one connected with the fan wheel f to operate before the one connected with the fan-wheela and at the predetermined time the hook f 11 of the spring will become disengaged from the fan-wheel f, when the weight F will pull down the handle F and the elements F and D will move to the positions shown in Fig. 9, the release mechanism to the right not becoming disturbed and the ratchet-wheel (0 sliding under the pawl (0 to permit the handle (Z2 to turn down and raise the chain H.

It will be noted that the element D is so counterweighted that the appurtenances at the furnace end of the chain H tend to pull the latter down when the said element is in a position as shown in Fig. 9, and when the spring a becomes disengaged from the fan-wheel a the handle (Z will turn up and the chain H will be lowered.

In case the moving elements are located as shown in Fig. 9 and the movable support-D is first pulled up to the position shown in Fig. 7 by disengaging the fan-wheel coacting with the support D, if it happens to be engaged there with, and then it is desired to turn up the handle F, which can be done whether the fan-wheel f is engaged or disengaged by the spring f by virtue of ratchet-wheel f sliding under its pawl, it will be found that the teeth F of the sector F cannot pass the teeth d of the movable support D, and to obviate this difficulty the movable support is modified, as shown in Figs. 3, 3", 3 or as shown in Figs. 10, 11, and 12, which latter has already been described. In Figs. 3*, 3, 3 a tooth like '1: of the removable support is pivoted on a pin 7", secured in the lugs P, that extend on the sides of a cavity 0, formed in the disk portion o of the movable support. The tooth is extended beyond the pin r to overbalance the front portion of the tooth, so that when the support is in the position shown in Fig. 7 or Fig. 3 the rear portion 9" will impinge against the lower surface 0' of the said cavity to be always in proper position when the moving elements are disposed, as shown in Fig. 7 and the likethat is, when the d rivingsector F is to engage the movable support to turn it from the position shown in Fig. 7. Now when, as shown particularly in Fig. 3", the sector F is moving in the direction of the arrow shown in said figure it will depress the pivoted tooth 1' out of the way, and when the sector F has passed beyond the tooth r the latter will assume its normal position.

It is evident that the movable support D can be placed in the position shown in Fig. & and used for lowering the chain H without any relation to the driving-sector F.
